Abstract
A sensor electrode (31) provided between an insulating substrate (21) and a counter electrode (27) includes a plurality of electrodes (32) arranged along a first direction and a plurality of electrodes (33) arranged along a second direction perpendicular to the first direction and insulated from the electrodes (32), and these electrodes (32, 33) are formed in the same plane.
Claims17
A touch panel substrate that is used as one of a pair of substrates between which an electro-optic element is sandwiched and that is provided with a position detecting electrode which detects, according to a change in capacitance, a position on coordinates as indicated by an object to be detected, the touch panel substrate comprising:
- an insulating substrate;
- an electro-optic element driving electrode which applies an electric field to the electro-optic element;
- and
- the position detecting electrode provided between the insulating substrate and the electro-optic element driving electrode and being insulated from the electro-optic element driving electrode,
- the position detecting electrode including a plurality of first electrodes arranged along a first direction and a plurality of second electrodes arranged along a second direction perpendicular to the first direction and insulated from the first electrodes,
- the first electrodes and the second electrodes being formed in a same plane.
